No Product Like It! Nothing Else Compares! You Will Be Amazed!Like countless others I was a bit skeptical. However, I said, perhaps this one may be a little better than all the other stuff I have tried. What I heard and experienced was truly revolutionary after I put it in my old truck. I was stunned! That's the God's truth. It runs like a much different engine. It was significantly quieter. It has not change after several thousand miles. It burns less gas. You simply must try it to truly believe and appreciate the fact that nothing comes close and you are adding years to your investment and this $$$$ in your pocket. No doubt, it truly pays for itself. You hear and feel the difference. In short, you will be thoroughly impressed and feel like YOU are the genius.

Frequently asked questions about additives.

1. What is in my engine oil?

All finished oils have a base oil that can be mineral or pure synthetic or a blend of the two. If the bottle says Full Synthetic then it has be, by law, a Group III, IV or Group V base oil that is "Synthetic". Group III and IV are the most popular oils.

Group V CharacteristicsGroup V base oil is everything that is left over from the group III and IV refining process's.

2. What are oil additives?

These oils contain up to a dozen different "additives" that can be friction modifiers such as ZDDP ( zinc ) and Moly are the two you probably have heard of. There are also additives to meet a particular demand for the oil. such as viscosity index improvers, antioxidants, corrosion inhibitors, detergents, anti-foam compounds and Alkalinity improvers.

Race oil and oils for daily drivers usually have a very different additive package. Race oil is designed to make the motor last a short period of time and they are not as concerned about antioxidants or alkalinity for the short time the oil is being used. Daily drivers however should have antioxidants and alkalinity improvers to make the oil last the 3 to 5,000 miles that the manufacturer suggests.
